The topic of this graduate thesis is the Reception of Grigor Vitez’s poetry and it’s role in the developmental course of Croatian children’s poetry. His 1956. collection Quail is a turning point in poetry because it cut off the teaching role. His verses gave up the role to replace it with the co-player role. Considering he was the founder of this new approach in children’s poetry, he was the inspiration for a whole new modern generation of Croatian children’s poets. In Vitez’s rich creativity for children we can point out many diverse units of his poetic thematic preoccupation. The author shapes songs about nature in a completely new way, creates the shape of an animal lullaby, elaborates the shape of a children’s riddle, creates lexical word games by pointing them with a witty twist and touches the possibility of an illogical, nonsensical poem. His poetry gains momentum and develops in a direction that didn’t have a visible path yet, but Grigor Vitez charts on the map of poetry something that until then wasn’t visible to us. He is the founder of modern children’s literature, as well as a synonym for different children’s poetry. In the research, a qualitative research paradigm was used. Besides the literature available online, available material from the Science and City Library of Zadar. Publishing houses and publishers of schoolbook material were contacted, for the purpose of researching the reception of Vitez’s poetry in schoolbooks, picture books, anthologies, historical reviews as well as contemporary poetry.
